Student protesters hold up a flag during a rally against the government demanding changes in the public state education system, in Santiago April 25, 2012. Chilean President Sebastian Pinera's tax reform to help fund an education overhaul could help center-right hopefuls ahead of next year's presidential race, but it won't stifle protests and might backfire by spurring calls for even higher spending. Pinera's reform proposal includes raising taxes on companies and lowering income tax for individuals. If approved, it would raise up to $1 billion a year in extra funding for education. Pinera unveiled the reform last week in response to massive student-led protests demanding free education and better distribution of the profits from a long copper boom in Chile, the world's No.1 producer.
